Abstract

A device, system and method may enable the obtaining of in vivo information other than or in addition to images from for example within body lumens or cavities, such as temperature, pressure, or pH from the gastrointestinal (GI) tract, where the data is typically transmitted or otherwise sent via an optical means to a receiving system.

Claims

1. A method for transmitting in vivo non-image information, the method comprising:

obtaining non-image sensor information from a sensor;

relaying the non-image sensor information to an illumination source contained within a container, wherein the non-image sensor information is used for modulating either the frequency of the optical output of the illumination source or the amplitude for changing the brightness of the optical output of the illumination source;

relaying the output of the illumination source to an area on an image sensor, the image sensor contained within the container; and

transmitting the image sensor information to an external receiver.

4. A method according to one of claims 1, 2, or 3 comprising:

displaying image sensor information.

5. The method according to one of claims 1, 2, or 3 wherein the non-image sensor information is obtained from the gastrointestinal tract.
